This change is readily accomplished by the mounting means provided.

For a better understanding of the invention, reference will be made to the accompanying drawings, in which,

Fig. 1 is afragmentary view in front elevaton of a portion of a batten constructed in accordance with the present invention;

Fig. 7 is a sectional View on the line 7--7 of Fig. 5; and

Fig. .8 is a fragmentary rear view ofthe section as illustratedin Fig. 5.

Referring now to these drawings, the batten 10 is illustrated as consisting of a beam 11, and an upper rail 12 connected by suitable cross-frame members 13. This batten is mounted for swinging movement on supports, not shown, and in the operation ofthe loom is swung forward and backward in the direction at right angles to its plane.

' Mounted on the batten in upper and lower rows are shuttles 14, these shuttles being movable in raceways defined by guide blocks 15. Each shuttle passes through a shed formed by warp threads which pass through areed 16 and there is a raceway for each shuttle on each side of each reed.

The shuttles illustrated are reciprocated by an actuator bar 17 carrying plates 18 adapted to be received in slots 19, formed in the ends of the shuttles. This .bar 17 is mounted in any suitable way between the shuttles of the upper and lower rows and at one end is attached to an upright arm 20 on a slide 21 connected by spaced rods 22 to an upper 23. These slides 21 and 23 are movable as a unit in guideways provided in the beam and the upper rail respectively, and the slides are reciprocated by means of a lever 24 carrying a pin 25, which enters the space between the rods 22. As the lever is swung, the slides 21 and 23 are reciprocated lengthwise of the batten and in their movement cause an endwise movement of the actuator bar 17. This bar is provided at one end with a pin 26 entering a slot 27 in a tubular cam .28, Whichcauses the bar to be rocked through 180 at appropriate intervals in its movement.

The actuator bar and the mechanism by which it is driven formnogpart. oftthe-pres shuttle. may be made as a single metal casting.

plates are carried out of engagement with the trailing ends of the shuttles of one row and into engagement with the leading ends of the shuttles of the other. Each plate then engages and carries that shuttle with the bar to'the end of the shuttle movement. On the return, the sequence of operations is reversed.

One type of batten section constructed in accordance with the present invention is illustrated in Fig. 3 and this section consists;

of apair of frame members 29 in the form of straps adapted to extend between the. beam and upper rail. Mounted across the straps are blocks 150: which together define a shuttle raceway for a shuttle in the lower row, and mounted on one of the straps are guide blocks 15b defining a raceway for a shuttle of the upper row. These raceways are illustrated in staggeredrelation and partially overlap, the blocks 156 being attached at one end to one of the strap members 29.

Mounted in the space between the strap members 1s areed 16 which may be attached to the upper guide block 15a and to a suitable crosspiece 30 at its upper end. This reed is detachable from the section.

The section is a complete unitary structure,.preferably made integral, with the exceptionof the reed, and the straps and the guide blocks may be made of wood or metal.

The guide blocks are channeled as indicated at 31 toreceivefflanges 32 on the base of the shuttles and these channels are smoothly finished to provide a su'itableraceway for the The complete section if of metal As convenient means of mounting the sections on thebatten, the beam may be provided with long tudinal ribs 31, and the strap members suitably channeled as indicatedat 32', so as to permit the channels to receive the ribs. Preferably the ribs and channels form a dovetail connection. The upper rail is also provided with a lengthwise rib33 and the'frame members 29 channeled at 34 so that these channels may receive the rib. Each of the framemembers 29 is also provided with threaded holes in which may be mounted bolts 35 which can be screwed into the holes to bear against the ribs 31 and I 33-to hold the sections in proper position.

WVith this arrangement, when the batten is-to be assembled for operation, the sections :are slippedon the-ribs and moved along api proximately to the positions they are to occupy. The first 'sectio'njis then placed in the desired position of adjustment and-secured there by tightening the bolts 35. This section may be one like that illustrated in Fig. 3. Then the next section is moved along until the free end of thefguide blocks 15b overlie the adjacent frame members 29 on operations are re eated until the entire group 7 of sections has een placed in proper relatwo positions.

It will be seen that theoperation of adjusting the sections in proper relation to. each other isvery simple, since each section determines the position of the section following it in the series, and the only adjustment that needs to be made accurately is the positioning of the first section, the others b-eing simply moved along the batten until the openings in their strap members'register with openings in the free ends 'of'the blocks of.

he preceding sections. When a change in he fabric is necessary, the bolts holding the sections in position are loosened, the connections between the sections removed and all of the sections slipped off the ends ofthe rods. The section illustrated in Figs. 3 and i is single in the respect that it carries a single raceway for shuttles in each of the rows. In

some instances, it may be'desirable to use a I section of larger size, which includes more than the one raceway in each row, For this purpose,the construction illustrated in Figs. 5 to 8, inclusive, may be employed.

In the arrangement, llustrated in-those figures, the top rail of the'batten is dispensed with and mounted on the rear face of the beam is a plate 38. Each batten section includes a pair of end frame members 39, which extend across the face of the plate 38 and have a recessor channel 40 in which the plate is snugly received. The'engagement of the i V end'walls of the channels with theside edges of the plate holdsthe section rigidly in upright position and adjacent sectionsare secured to the batten by means of'strap members 41, each of which is attached to the "i beam by means of a bolt 42 threaded into an opening in the plate 38. Each strap member overlies an end frame member 39 of two adjacent sections and when the bolts are ti htened, the sections are clamped to th rear face of the beam.

The upper ends of the end frame members 39 are connected by a frame member 43, which serves as a part of the upper rail with which these battens are usually provided.

1 Also extending across the members 39 is a lower frame member ii resting on the'upper ed'ge of the plate 38 and-partially overlying thatplate. Connecting the members -43 and '4 l b'etween-the end frame'members '39, are

straps 45; 'The spacing between the straps and the'en'd frame members and'between adqjacen't' straps is uniform.

Attached to each endframe member 39, i

and also attached to the adjacent strap mem- "ber45,'a're guide blocks 16a,:andthese guide blocks are arranged in pairs to define 'raceways for a shuttle in the lower row. Connecting the strap members 45 are similar guide blocks 46?), which defineia raceway for I a shuttle in the upper row. Also mounted on each end frame member 39 projecting outwardly therefrom are half-blo'cks47, each member 39 carrying a pair blocks, as illustrated. j

IWith this arrangement, whenithe batten-p ist'obe assembled, the first section'is placed I ofthese half-Q in proper positionand the'next'section is v moved. upvagainst it until the ends of the wo frail members 43 of the sections lie in contact. ,Then the sections are secured to the batten by means of the clamp plates 41. In

It sometimes happens that. a shuttle may be injured or broken and 5 replacement of a batten section required,

This does not happen frequently, but with the modified construction a single section with the injured shuttle can be readily removed,

Whereas with the construction shown in Figs- 3 and 4, all of the. sections between that to be removed and one end of the batten would have to be taken 011". to permit the removal of the one. injured.

In each of the section constructions illustrated, the section is a complete unitary Sir 11c:- ture which may be integral throughout, with the exception of the reeds, and those sections may be made of cast metal. As the sec.- tions are, all of the same construction, the cost of their production is relatively low, since they are made from they same pattern- This seotional batten construction affords many importantadvantages above pointed out, since i it avoids the necessity for keeping several battens in stock and as the sections required for any batten are relatively cheap, the in- Vestment in sections necessary for fabrics of different Widths does not represent an item of any considerable importance in overhead. Furthermore, this investment is repaid many times in the course of use by reason of the saving in time, required to change the loom from one fabric to another, since that change can be effected in a short time Without removing the entire batten.

While, I have shown the sections with one suitable arrangement of the guide blocks, it is evident that other arrangements may be employed without departing from the invent tion.

This application is a continuation in part of my co-pending application, Serial No. 211,885, filed August 10, 1927.
